ok i got a ford racing gt40 motor the 345hp version.
-cobra intake
-75mm tb
-1.7 rockers
-24lb injectors
-matched mass air
i figured that setup would work pretty nice.
well i got a supercharger powerdyne set up with a 9lb pulley.
i has the stock fmu tht comes in the kit.
my research so far.....
-iv read on the internets that a 255lph pump screws things up with the fmu.
-some are saying 24lb injectors with a 155lph(?) pump works great. (i find it hard to belive)
need some input here.
-i was thinking getting bigger injectors ditching the fmu get the bigger pump.
-or run this set up get the 155 pump and add a water meth kit.
all info and help is appreciated!

Ditch the fmu, and get a 255 pump possibly a inline pump also, 36lb min. I would run 42lb and get it tuned! Remember the fuel system is one part on the car you can never have too much!

+1 42!bs injectors maybe a Bosch inline pump then the 255lb in the tank and a good adjustable fuel pressure regulator

+2 take it to AED ![[patriot]](graemlins/patriot.gif) If you decide to get it tuned call your tuner and have them recommend the proper fuel system mods. This will save you a lot of time and money buying the wrong shit.
If you decide not to get it tuned.. then run the FMU (make sure you have the right calibration for 24's), 24's, 255lpr pump, and get a BTM.

is there a special mass air meter needed for the supercharger? or would the one calibrated for 42lb injectors that 2coupes is selling work?

1> preferred method -
ditch the fmu. pick up a 255 and 42# injectors and msd6 btm.
2> secondary method
keep the fmu but upgrade to 36's with the 255 as msd6 btm.(this was a very common setup)
I have just moved here from Houston were I used to tune supercharger application fox cars. Mind you this was several years ago but after tuning nearly 50 I can say beyond a shadow of a doubt the 24's will never work with that combo.
For your boost level h2o/meth is completely unnecessary
